Patent FR-2241682-A1 (FR)
Title: Opening-closing arrangement for up-and over garage doors - for selective remote control needs no external energy supply
IPC: E05F1/10
Filed: 1974-08-23
Abstract: The arrangement is for doors with a horizontal swive axis having springs, and balance weights, to compensate for part of the weight-originated torque of the door. A helical spring stores kinetic energy, which may be utilized for the operation of the door, by freeing a blocking element. The force of the spring engages on the door via an element which may be turned about a support and which is held with it on a section fastened to the door. The element may be moved between a position in which the spring supplies too little torque and a second position in which a longer arm is available for the spring force, and hence a torque excess results.

Title: Automatic focusing slide projector - uses photocells and light reflected from slide to position objective lens
IPC: G03B3/12
Filed: 1975-12-17
Abstract: The automatic focussing device for a slide projector uses photodetectors and a light source reflecting from the slide to measure the slide position and to appropriately operate the servo-mechanism controlling the position of the objective lens. The light source is focussed onto the slide and reflects onto photodetectors. The signals from the photodetectors are processed to determine in which direction the stick is mis-placed. The result controls a motor which is linked to an eccentric cam. The rotation of this cam moves the mounting of the projector objective lens until the signal from the photodetectors is again nul. The nul position can be set by a remote control device which activates a worm drive that adjusts the position of the objective in its mounting.
